Mill stream close to the Wülfing Museum, autumn 2011. Usually a water power plant is run by water from this mill stream. And yes, if the mill stream is full the water floats beneath the red house. In autumn 2011 the mill stream was empty because it was so dry that all the water had to be kept in the river Wupper. In February 2013, a turbine in the water power plant burnt. Luckily there were no damages in the museum above. During the repair of the turbine there was no water in the mill stream for a long time.
